I'm not sure how to get the current build to work. I would like to because I use linux and there is no build for dc-netplay-4.0-652 on linux. Also I wanted to take advantage of the "faster" netplay.

I have everything set up just like I have with dc-netplay-4.0-652 and it runs extremely jittery. dc-netplay-4.0-652 works perfectly, literally no lag at all. I've followed every guide about how to set it up to get reliable online play from the dolphin site.

So what's going on here?

Literally every single game I played on dc-netplay-4.0-652 was perfectly smooth, we only got a few lag spikes.

I played a match on smash ladder today and it was pretty smooth other than a few lag spikes which is expected. The other play was in 2 states away from me and I lagged really bad while playing my brother a city away. I'm guessing this is because of my router, but the older 652 build didn't have an issue with the router?

I would guess that spamming packets less often would cause some jitter on a wireless connection.
